I have been with my girlfriend for 8 months. My gf is the manager at a major retail store. There is a woman who she has mentioned before that was her assistant manager at this chain of stores when she was living in a different town. This women is now the manager at that store which is about 1hr away from where we live. Well for the past two weeks all the store managers in have been traveling to all the stores in their district to do a big store reset. Therefore, she has seen this woman...I will call her S on a daily basis. Each night when my gf gets home I have to hear about S. S gets up each morning and cooks breakfast for her family, S is great at this and that. On Friday S told my gf that she was an amazing person. I have heard about S in the past how her husband stopped having sex with her and how S cheated on her husband with some guy. A little back story...about 8 years ago my gf and S were training for a 5k. My gf’s now ex wife forbid her from hanging out with S. My gf said it was because S was really attractive and in good shape which made her ex wife insecure. I don’t want to be that person that feels jealous and insecure. My gf’s ex wife was over the top jealous and made my gf cut off all her female friends. That’s not me and I don’t want my gf to think I’m going to be the same way. I will add that S has no social media so I have no idea what she looks like. Today before she left for work she could tell something was wrong. She said I seem unhappy lately. I didn’t want to bring up my feelings right before she went to work. Any advice?
